Rationale: The nurse should instruct the parent to use a peak flow meter daily to monitor the child’s respiratory status and detect early signs of an asthma attack.

Correct Answer: B

Rationale: The correct instruction that the nurse should include is to keep the child on bed rest for 12 hours following a cardiac catheterization. This is important to prevent bleeding at the insertion site and ensure proper healing. Allowing the child to bathe soon after the procedure, maintaining a pressure dressing for only 8 hours, or resuming regular activities the day after the procedure can increase the risk of complications such as bleeding or infection.

Correct Answer: C

Rationale: It is essential to give insulin at room temperature to prevent discomfort during administration. Cold insulin can cause stinging and pain, which can be avoided by allowing the insulin to reach room temperature before administration. Storing insulin in the refrigerator is correct for long-term storage, but it should be brought to room temperature before use. Rotating injection sites is important to prevent lipohypertrophy, a condition characterized by fatty lumps that can develop if injections are consistently given in the same area. Administering insulin within 30 minutes of a meal is generally recommended to match the insulin peak action with the peak glucose levels after eating, but giving insulin at room temperature is more crucial to ensure comfort and proper absorption.

Correct Answer: C

Rationale: The primary and most serious adverse effect of heparin is bleeding. However, discolored urine can indicate bleeding into the urinary tract, which is a potential adverse effect of heparin therapy. While changes in heart rate (HR) and blood pressure (BP) can occur due to various reasons, discolored urine specifically points towards a potential adverse effect related to heparin therapy.

Correct Answer: B

Rationale: The most crucial statement to include when teaching a patient prescribed metronidazole (Flagyl) is to avoid alcohol consumption. Mixing metronidazole and alcohol can lead to a disulfiram-like reaction, causing severe symptoms such as nausea, vomiting, and headache. Therefore, it is essential to emphasize to the patient the importance of abstaining from alcohol while taking this medication to prevent adverse reactions.
